Benefits and Issues:
➊ By “black” is not meant pure black; rather, this flag was made of striped cloth and was square-shaped. (Jami‘ at-Tirmidhi, al-Jihad, Chapter: What Has Been Related About Banners, Hadith: 1680)
➋ In war, the flags of different battalions can be of different colors.
➌ Both (rayah) and (liwa’) mean “flag.” In this respect, they are synonymous words; however, according to one opinion, (rayah) is a large flag and (liwa’) is a small flag (Hashiyah Sunan Ibn Majah by Muhammad Fu’ad ‘Abd al-Baqi). We have translated according to the other opinion.
